Synthesize Multi Source Evidence
Combine independent evidence sources into one careful claim.
- Observation vs. inference: Forensic work starts by separating what was seen from what is concluded.
- Evidence identity: Labels, photos, and logs keep evidence tied to the right source.
Prerequisites are inferred: pending teacher review.

Combine independent evidence sources into one careful claim.
Use the synthesis figure. Which claim is strongest?
Reviewed- A.The claim based on the first clue found at the scene
- B.The claim that keeps only the evidence that agrees with it
- C.The claim that names a suspect most confidently
- D.The claim supported by scene, lab, and history evidence

Answer: D. The claim supported by scene, lab, and history evidence
- Step 1: Use multiple sources: The strongest claim uses several independent sources.
- Step 2: Avoid ignoring data: Ignoring a source weakens synthesis.
Why it's right: A multi-source claim is stronger than a one-clue claim.
- A: The first clue is one source; a synthesis has to use all three.
- B: Dropping evidence that disagrees makes a claim look strong and hides conflict.
- C: Confidence in the wording is not the same as support from evidence.

- In Unit 1.3 Open Investigation, this skill turns class evidence into a result another person can check.
Fill these in as you work through the lesson.
- Evidence source (place the data came from):
- Converging evidence (different clues pointing same way):
- Contradiction (evidence that does not fit):
- Synthesis (combining parts into a whole):
A synthesis claim is strongest when evidence sources point to the same answer and contradictions are .
- Which sources agree?
- Which source conflicts?
- What claim fits the most evidence?
Given a photo log, biomolecule test, and witness statement, write the one claim they support and one limit.
